Rotatable counter chair



Patented Apr. 26, 1949 UNITED STATES PATENT OFFICE ROTATABLE COUNTER CHAIR Yvon D. Smith, San Francisco, Calif.

Application November 23, 1946, Serial No. 711,954

2 Claims.

This invention relates to a counter chair.

The object of this invention is to provide a counter chair which may be swung around by a party leaving the same and which chair will automatically return back to its normal position facing the counter.

Another object of this invention is to provide a novel mechanism which may be attached to any counter seat and a standard pedestal supporting the same, which mechanism shall operate to return the seat to its normal position facing the counter.

Another object of this invention is to provide a mechanism of the type described which can be manufactured as a separate unit and placed on the market with or without the standard pedestal.

Another object of this invention is to provide a device which is simple, durable and efficient for the purpose intended.

Other objects and advantages will appear as the specification proceeds and the particular features of the invention will be specifically pointed out in the appended claims.

My invention is illustrated in the accompanying drawing in which:

Fig. 1 is a side elevation of a counter chair constructed in accordance with the teaching of this invention;

Fig. 2 is a side elevation of the chair returning mechanism, some parts being broken away;

Fig. 3 is a front elevation of the chair returning mechanism;

Fig. 4 is a horizontal cross-section of said mechanism taken on the line 4-4 of the Fig. 2; and

Fig. 5 is a front elevation of the chair returning mechanism showing the parts thereof in different position.

In detail, my counter chair comprises a seat l and a back 2 which are attached to a seat returning mechanism 3. The latter permits the seat to be swung around by a party intending to use the same, or leaving it, and will return said seat to its normal position facing the counter. The mechanism 3 is aflixed in the hollow top of a standard pedestal 5 which supports said mechanism and seat and which is located in close proximity to the counter.

The mechanism 3 includes a round shaft H], the top of which carries a spider ll attached to said top by a set screw I2, which spider supports the seat I.

The shaft Iil passes through a disk 14 which is of the same diameter as the top of the pedestal 2 5. The disk M has a shoulder it on the periphery thereof which fits into the hollow top of said pedestal;

A block H is welded or otherwise secured to the disk [4, which block has a centrally located bore l8 through which the shaft l0 passes with freedom of rotation and longitudinal movement.

Two supports 20 are welded to the disk l4 and to the block H, at the sides thereof. The supports 29 extend downwardly beyond the block l1 and rotatably carry in the free ends thereof a dowel pin 2 I made of hard steel.

The lower end of the shaft in is bevelled as at 22 and has a stop 24 which is substantially square in cross-section and extends downwardly from the lowermost point of said bevelled end.

As shown in Fig. 2, the bevelled end 22 of the shaft Ill rests on the pin 2|. When the seat is rotated, the shaft Ill rotates therewith and the bevelled end 22 rides on the pin 21 forcing the shaft ID with said seat upwardly as shown in Fig. 5. The seat may be rotated in any direction until the stop 24 strikes the pin 2|. The force of ravity pulls the seat and the shaft l0 downwardly and forces the bevelled end 22 to ride on the pin 2| thus returning the seat to its normal position.

As the pin 21 rotates in the supports 20, when the bevelled end 22 rides upon said pin, the edges.

of said bevelled end come in contact with different points of said pin, thus preventing the formation of grooves thereon which would ordinarily be formed by the said edges by sliding over the same path if said pin were stationary. The supports 20 abut the inner wall of the pedestal thus preventing the lateral displacement of the pin 2|. The block I! has an extension 25 which also abuts the inner wall of said pedestal. The mechanism 3 having three surfaces abutting the inner wall of said pedestal is thus prevented from tilting therein. A screw 26 passing through the pedestal wall into the block extension 25 prevents said mechanism from rotating in said pedestal.

Having thus described my invention, I claim:

1. A swingable counter chair comprising a seat, a hollow pedestal, and a mechanism for returning said seat to its normal position; said mechanism including a disk; a block attached to said disk; a shaft slidably and rotatably arranged in said block; said shaft carrying said seat on its upper end and having its lower end bevelled; a pair of supports depending from said disk; a pin rotatably carried in the lower ends of said supports; said pin being so positioned that the upper portion of the bevelled end of said shaft normally rests on the pin, said disk closing the upper end of the pedestal and means for securing said block to the pedestal.

2. A swingable counter chair comprising a seat, a hollow pedestal and a mechanism for returning said seat to its normal position; said mechanism including a disk fitting the top of the pedestal; a block attached to said disk so as to abut the inner Wall of said pedestal; a shaft slidab'ly and rotatably arranged in said block; said shaft :carrying said seat on its upper end and having its lower end bevelled; a pair of supports depending from said disk and abutting the inner wall of said pedestal; a. pin rotatably carried by the sup- 4 ports in their lower ends; said pin being so positioned that the upper portion of the bevelled end of said shaft normally rests on the pin; and means for securing said block to the pedestal.
